Herbs Used for Parasites

Page content

Parasites are actually more common than most people think. The diet many consume in the developed world consists of a lot of beef, pork, and other meats that are not always cooked completely. Raw animal flesh, such as sashimi, is also commonly consumed. In some cases, a patient may have a parasite and not even realize it. Intestinal parasites are the most commonly seen, such as tapeworms and pinworms. Once they root themselves in the intestinal tract, they parasitically feed off of the host’s energy and nutrients, which can result in a variety of medical problems for the host. There are prescription antiparasitic drugs available, however, there are also several different herbs for parasites that patients may use after speaking to their doctor to help rid themselves of the parasite.

Black Walnut

This herb is purported as a powerful antiparasitic and antifungal herb. The inner bark of the walnuts are the most potent. Using the raw herb or a strong tincture is typically recommended for parasites. Not much is known about the safety of this herb. This herb should never be used during pregnancy and topical use may not be safe. Those with a tree allergy should avoid this herb.

Grapefruit Seed Extract

This herb has been touted as an effective antiparasitic, antibacterial, antiviral, and antifungal herb. This herb is said to be generally safe, however, those with an allergy to citrus fruits should avoid this herb. Those taking high cholesterol medications and anticoagulants should also avoid this herb.


Garlic is often not thought about as one of the possible herbs for parasites. In addition to antiparasitic properties, this herb is said to also have antibacterial, antifungal, and antiviral properties. In order to get the best effect, patients should use raw, fresh cloves, and preferably organic. Body and breath odor, as well as allergic reactions are the most common safety concerns. However, other possible side effects may include dizziness, headache, fever, asthma flares, increased sweating, itching, chills, and runny nose. Other side effects may occur. Garlic should never be applied to the skin. Bleeding is a serious side effect that is possible with this herb. Patients taking a blood thinner, anti-platelet medication, or non-steroidal anti-inflammatory drug, may not be able to take this herb.

Those sensitive to stomach irritation and those with stomach ulcers, should use extreme caution when using garlic.
